    Field-control, phase-transitions, and life's emergence

    Instances of critical-like characteristics in living systems at each organizational level as well as the spontaneous emergence of computation (Langton), indicate the relevance of self-organized criticality (SOC). But extrapolating complex bio-systems to life's origins, brings up a paradox: how could simple organics--lacking the 'soft matter' response properties of today's bio-molecules--have dissipated energy from primordial reactions in a controlled manner for their 'ordering'? Nevertheless, a causal link of life's macroscopic irreversible dynamics to the microscopic reversible laws of statistical mechanics is indicated via the 'functional-takeover' of a soft magnetic scaffold by organics (c.f. Cairns-Smith's 'crystal-scaffold'). A field-controlled structure offers a mechanism for bootstrapping--bottom-up assembly with top-down control: its super-paramagnetic components obey reversible dynamics, but its dissipation of H-field energy for aggregation breaks time-reversal symmetry. The responsive adjustments of the controlled (host) mineral system to environmental changes would bring about mutual coupling between random organic sets supported by it; here the generation of long-range correlations within organic (guest) networks could include SOC-like mechanisms. And, such cooperative adjustments enable the selection of the functional configuration by altering the inorganic network's capacity to assist a spontaneous process. A non-equilibrium dynamics could now drive the kinetically-oriented system towards a series of phase-transitions with appropriate organic replacements 'taking-over' its functions.Comment: 54 pages, pdf fil

    The Global People toolbook: managing the life cycle of intercultural partnerships

    Get PDF
    This Toolbook has been designed for those who are planning and running international projects and who feel a need for guidance. It has its origins in a major educational project, the eChina-UK Programme, that created new collaborations between UK and Chinese Higher Education Institutions around the development of e-learning materials. The rich intercultural learning that emerged from that programme prompted the development of a new and evidence-based set of resources for other individuals and institutions undertaking international collaborative projects. Although the main focus of the work is on intercultural effectiveness in international contexts, we believe that many of the resources have a more general value and are useful for those planning collaboration in any situation of diversity – national, regional, sectoral or institutional

    Energy Harvesting Wireless Communications: A Review of Recent Advances

    Get PDF
    This article summarizes recent contributions in the broad area of energy harvesting wireless communications. In particular, we provide the current state of the art for wireless networks composed of energy harvesting nodes, starting from the information-theoretic performance limits to transmission scheduling policies and resource allocation, medium access and networking issues. The emerging related area of energy transfer for self-sustaining energy harvesting wireless networks is considered in detail covering both energy cooperation aspects and simultaneous energy and information transfer. Various potential models with energy harvesting nodes at different network scales are reviewed as well as models for energy consumption at the nodes.Comment: To appear in the IEEE Journal of Selected Areas in Communications (Special Issue: Wireless Communications Powered by Energy Harvesting and Wireless Energy Transfer

    Key factors affecting transnational knowledge transfer in the context of the Euroaid Asia programme

    A thesis submitted for the degree of Master of Science by research of the University of BedfordshireThe thesis aims to identify and verify the key factors affecting transnational knowledge transfer (TKT) in the context of the EuroAid Asia Programme. This study extends the existing research on knowledge transfer (KT) by investigating the neglected area of TKT, an area which needs better understanding, given the rapid development of TKT. Compared to the KT at the individual, group, or organizational level, TKT is both more complicated to comprehend, and has received less attention. This study begins with a literature review of the definition of knowledge and KT, analysis of KT at different levels, and summary of a comprehensive set of factors that may influence KT. Then, in order to empirically explore the key factors affecting TKT in the EuroAid Asia Programme and to evaluate the relative importance between factors, an international Delphi survey is employed. Through the two rounds, experts mentioned twenty-four factors and provided explanations for their views. Based on these survey results, a factorial model is developed. The verified factors and the proposed model could help project participants better understand the process of TKT, remind them what key factors really influence the process of TKT and urge them to make an active effort to properly assess each factor before prioritizing the factors for management attention

    With its July 2015 announcement of the Second Chance Pell Pilot Program, the U.S. Department of Education ushered in what could be a new era of expanded opportunities for postsecondary education in our nation's prisons. The Second Chance Pell Pilot makes students incarcerated in state and federal prisons eligible for need-based financial aid in a limited number of authorized sites—meaning postsecondary education is likely to become a reality for an increased number of the more than 1.5 million people in prisons nationwide.Research shows that—among other benefits to individuals, families, communities, and prisons—incarcerated people who participate in prison education programs are 43 percent less likely to recidivate than those who do not. This report offers lessons from the field on the implementation of these programs in corrections settings across the country
